摘　　要：为促进固废材料的资源化利用,研究采用固废材料全替代水泥并掺加不同掺量的纳米SiO_(2)和纳米CaCO_(3)制备纳米固废混凝土,进行纳米固废混凝土的抗折强度试验和弯曲疲劳试验。试验结果表明,纳米材料可以增强固废混凝土的抗折强度并改善其弯曲疲劳性能,纳米SiO_(2)和纳米CaCO_(3)分别在掺量为2%和1%时对固废混凝土的抗折强度和疲劳性能的改善效果最显著。研究可为固废混凝土在道路、桥梁以及港口码头等交通基础设施中的推广应用提供理论依据。To promote the resource utilization of solid waste materials,nano solid waste concrete is prepared by re⁃placing cement with solid waste materials and adding nano-SiO_(2) and nano-CaCO_(3) with different amounts.The flexur⁃al strength and flexural fatigue of nano solid waste concrete are investigated.The results show that nanomaterials en⁃hance the flexural strength and improve the flexural fatigue properties of solid waste concrete,and nano-SiO_(2) and na⁃no-CaCO_(3) have the most significant effectiveness on the flexural strength and flexural fatigue properties of solid waste concrete when the content is 2%and 1%,respectively.
